Must and wines

analysis of musts and wines by ICV

Regular monitoring by a "control plan" approach allows the monitoring of the desired development of products.

For this, the laboratories of the ICV Group offers a menu of analyses adapted to different stages in the life of the wine.

Common vinification and aging analysis

From alcohol fermentation to complete assessment of the cellar, many technical analyses are routinely performed: volatile acidity, glucose and fructose, alcoholic strength by volume, free and total SO 2, active SO 2 , total acidity, pH, colour intensity, hue, malic acid and lactic acid, polyphenols ...


The results of rapid tests

We offer various solutions for collecting your samples:

  • collection at your winery by the enologist or courier
  • collection from agreed points nearby

The deadlines for carrying out the analyses are only a half day during harvest and 1 day outside the harvest period.
